Pinpoint Test C: A Single Power Window Is Inoperative - RH Front Window
WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
- C1 CHECK THE RH FRONT WINDOW OPERATION FROM THE LH FRONT WINDOW CONTROL SWITCH
- Ignition ON.
- Operate the RH front window from the LH front window control switch.
- Does the RH front window operate from the LH front window control switch?
- Yes: GO to C2 .
- No: GO to C3.
- C2 CHECK CIRCUIT CPW14 (VT/WH) FOR VOLTAGE
- Ignition OFF.
- Disconnect: RH Front Window Control Switch C604.
- Ignition ON.
- Measure the voltage between RH front window control switch C604-3, circuit CPW14 (VT/WH), harness side and ground.
- Is the voltage greater than 10 volts?
- Yes: INSTALL a new RH front window control switch. REFER to WINDOW CONTROL SWITCH . TEST the system for normal operation.
- No: REPAIR the circuit. TEST the system for normal operation.
- C3 CHECK CIRCUITS CPW20 (WH/OG) AND CPW19 (VT) FOR VOLTAGE AND GROUND
- Ignition OFF.
- Disconnect: RH Front Window Motor C608.
- Ignition ON.
- Measure the voltage between RH front window motor C608-1, circuit CPW19 (VT), harness side and RH front window motor C608-2, circuit CPW20 (WH/OG), harness side while operating the RH front window control switch in the DOWN then UP positions.
- Is the voltage greater than 10 volts in both switch directions?
- Yes: INSTALL a new window regulator and motor. REFER to WINDOW REGULATOR - FRONT DOOR . TEST the system for normal operation.
- No: GO to C4 .
- C4 CHECK THE RH FRONT WINDOW CONTROL SWITCH
- Ignition OFF.
- Disconnect: RH Front Window Control Switch C604.
- Carry out the window control switch component test on the RH front window control switch.
Refer to appropriate SYSTEM WIRING DIAGRAMS article for component testing.
- Did the RH front window control switch pass the component test?
- Yes: GO to C5 .
- No: INSTALL a new RH front window control switch. REFER to WINDOW CONTROL SWITCH . TEST the system for normal operation.
- C5 CHECK CIRCUITS CPW20 (WH/OG) AND CPW19 (VT) FOR AN OPEN
- Measure the resistance between RH front window control switch, harness side and RH front window motor, harness side using the following chart:RH FRONT WINDOW CONTROL SWITCH CHART
RH Front Window Control Switch Circuit RH Front Window Motor C604-5 CPW20 (WH/OG) C608-2 C604-2 CPW19 (VT) C608-1 - Are the resistances less than 5 ohms?
- Yes: GO to C6 .
- No: REPAIR the circuit. TEST the system for normal operation.
- Measure the resistance between RH front window control switch, harness side and RH front window motor, harness side using the following chart:
- C6 CHECK CIRCUITS CPW20 (WH/OG) AND CPW19 (VT) FOR A SHORT TO GROUND
- Measure the resistance between RH front window control switch C604-5, circuit CPW20 (WH/OG), harness side and ground; and between RH front window control switch C604-2, circuit CPW19 (VT), harness side and ground.
- Are the resistances greater than 10,000 ohms?
- Yes: GO to C7 .
- No: REPAIR the circuit(s) in question. TEST the system for normal operation.
- C7 CHECK CIRCUITS CPW12 (GN/OG) AND CPW13 (BN/YE) FOR AN OPEN
- Disconnect: LH Front Window Control Switch C504A.
- Measure the resistance between LH front window control switch, harness side and RH front window control switch, harness side using the following chart:LH FRONT WINDOW CONTROL SWITCH REFERENCE
LH Front Window Control Switch Circuit RH Front Window Control Switch C504A-3 CPW12 (GN/OG) C604-1 C504A-8 CPW13 (BN/YE) C604-6 - Are the resistances less than 5 ohms?
- Yes: GO to C8 .
- No: REPAIR the circuit. TEST the system for normal operation.
- C8 CHECK CIRCUITS CPW12 (GN/OG) AND CPW13 (BN/YE) FOR A SHORT TO GROUND
- Measure the resistance between RH front window control switch C604-1, circuit CPW12 (GN/OG), harness side and ground; and between RH front window control switch C604-6, circuit CPW13 (BN/YE), harness side and ground.
- Are the resistances greater than 10,000 ohms?
- Yes: INSTALL a new LH front window control switch. REFER to WINDOW CONTROL SWITCH . TEST the system for normal operation.
- No: REPAIR the circuit. TEST the system for normal operation.
